Galaxy® Tension is the world’s first technology that enables accurate 3D scanning and mapping of tension, or stress, in the internal structure of rough diamonds. The presence of tension within a rough diamond endangers the integrity of the stone during laser sawing. Laser cutting on high tension areas can enlarge the inclusion, create new cracks, or even cause the rough diamond to shatter. According to feedback from diamond manufacturers, 10 to 20% of rough diamonds with detected medium or high-tension areas are damaged in some way during the laser sawing process. Galaxy® Tension provides precise, color-coded detection that displays the actual, physical location of tension areas and the intensity of the tension within the diamond, with no distortions caused by reflections or other visual disturbances. Galaxy® Tension, used with Advisor® rough planning software, adds a new dimension to rough diamond planning, enabling manufacturers to consider the actual location of tension in rough diamonds at a much earlier stage of the production process, ensuring safer, more effective and more profitable planning and sawing.
